Hi there:
Happy to help you out here. Based on your project description, I recommend using WordPress for your blog. WordPress is the world's leading blogging platform, and is powerful enough that it can be extended to do whatever you may wish to do with the website in the future.
It is also one of the easiest Content Management Systems to learn and use. You would have no problems learning how to add posts and pages to your blog.
If you wish, I can do up a concept of what your blog could look like?
Look forward to your reply.
Regards
Jon
